Hi i love my Jp50 except that is has some serious tuning problems.
I even changed to new strings but it was still the same thing.

Now the thing is i cannot do bends, i cannot use the whammy bar, or anything like that or it will go out of tune instantly, to me it seems like the bridge is too loose.

If i put my whammy bar in and just move it about around the hole then i can see on a tuner that it changes tuning.

If i bend like ½-1 step then it goes out of tune as well and it's really bugging me.

I did put new strings on it, and the nut looks perfectly fine, so i think that it's becaus the bridge is too loose, is there any way to make it "not so moveable :D"

Thanks and sorry for my bad english :)

I know this sounds like a dumb question but, did you tighten the knobs on the back of the tuning machines?
Did you stretch out the new strings when you put them on?
What gauge of strings did you use?

Yup the locking tuners are locked :) and its not wounded around the tuning thing more than ½ time.
What do you mean with stretching them out? the older strings which came stock had the same problem.
I'm using ernie ball 10's

What he means is that when you put a new set of strings on a guitar it will take some time for them to stretch out. You should go up and down each string bending and then retuning your guitar until they settle in which should take about an hour, I usually do this then tune them all up a quarter tone and let the guitar sit for the hour. But since you said you had this issue with the old strings give CS a call and they will help you out.

I use a more aggressive stretching method...Press the string down on lets say the 5th fret with your left hand....then tug the string upward with you right hand, gripping it around the neck pickup. Do this several times with each string. Note that you need to pull with less force on the higher strings. Be careful on the b and high e strings.

If you are looking to be able to lock it down you can use one of these: http://www.tremol-no.com/

Or you could also carefully place a wood block behind your trem block to stop it from moving, like this: http://media.photobucket.com/image/wood behind trem block/JudokaUSA/Block_Bridge.jpg

But I am sure that you would want to use the guitar at it's full potential. If I were you I would really check that nut and make sure the strings aren't binding up. That is usually the problem with these systems. If that isn't the case check your saddles and make sure that there are no grooves that shouldn't be there, like grooves made by string wear. Another major problem with these systems is that it is a floating trem which means your string tension and your spring tension must be the same. If you are not familiar with this kind of set up look up any videos on floyd rose setups and that may help! Good luck and I hope this helped! :D

I think I would get hold of Pat Park at Sterling By MusicMan and ask for help with this issue. Pat also hangs here frequently and could answer anytime. Here's an excerpt from the website ;

Contact us at 714-532-6657 or by email at [email protected] to obtain a Return Authorization number. We can also provide some assistance by phone or email, but if your instrument does require service you will need to ship it to us:

Give them a call Monday morning. Your Sterling is warranted for one year if you're the original purchaser.

Alternatively, you could take the guitar to a reputable guitar technician in your area and ask for advice or help with the problem. The problem here is that we can't SEE what is going on with your bridge and so help is difficult to provide. For instance, when you say the bridge is moving, what does that mean? Is it moving normally like a tremolo is supposed to? Or is it lose in the mounts? Also, did you change string guage? If so the neck and trem springs would/could require adjustment. There are alot of variables with a floating tremolo. So my advice is to get hold of Pat Park or sterling at this point, and he can advise on further course of action.

I'm from denmark and i bought it from Guitar Center USA, so i don't really think i can ship it to the US it would be so expensive.
But by the bridge moving i mean like if you used the tremelo, like up and down, you can just put the tremolo bar in and the weight of the tremolo bar will change the tuning abit.
But i'll try to stretch out the strings then :)

Did you change string guage? Like from 9's to 10's? Is the position of the temolo bridge plate raised or different from where it was from the factory? Did changing strings change the position of the bridge plate relative to the body?

Also suggest you put your country/location in your user data so people ca see where you're from. ;)

You never did say what string gauge you are using.
My AL with trem is fine with 10-46 Slinkys.
Try some lubricant in the nut slots.
Such as a teflon based lubricant like Tri-Flo.
Tri-Flow® Pin Point Lubricator - It's refillable!
